Deformation and tearing of blast-loaded stiffened square plates

Stiffened Plates Subjected to Uniform Blast Loading/Išskirstytąja Sprogimo Apkrova Veikiamos Sustandintos Plokštės

“…Other investigators have performed similar analyses (Xu et al 1991;Nurick et al 1995;Pan et al 1997;Rudraptana et al 1999). …”

Submarine hull integrity under blast loading

“…The explosion loading is either applied to the structure through empirical laws [4][5][6][7][8][9][10] or pressure gauge measurements [11][12][13]. The pressure loading from the explosive charge is assumed to be a rectangular pulse uniformly distributed over the plate surface [4][5][6][7][8] or is idealised as triangular [13][14] or exponentially decaying empirical laws [9][10]12]. A new tendency seems to appear with the fully coupled fluid/structure models where the detonation of the explosive, the air blast shock propagation, the interaction of the blast with the structure and the structure response are computed [15][16], which must be caused by the need of a closer representation of physical phenomena and the rise of computational power.…”

Response of Armour Steel Plates to localised Air Blast Load – A Dimensional Analysis

“…One vein through which this goal is achievable is the right choice of material. In fact, a considerable body of literature exists on the performance of steel, aluminium and composite plates subjected to uniformly impulsively (generated by far field explosives) blast, or localised blasts [1], [2] (generated by near field explosives), assessed numerically, experimentally [3]- [5] and theoretically. While the ballistic energy absorption capacity of some materials may be insufficient due to low ductility, low strength and weak hardening [6]- [8], other materials such as high strength ARMOX steel are more promising as they possess excellent ballistic performance due to high strength and ductility thus high energy absorbing capacity.…”
